Summary
Built in 1988 by the USDA NRCS, this earth dam stands at a height of 19 feet and spans 580 feet in length, with a storage capacity of 79 acre-feet. The primary purpose of this dam is to mitigate the risk of flooding along Big Creek, providing protection for the surrounding area.
With a drainage area of 334.72 square miles, Big Creek-Hurricane Creek R-6 has a maximum discharge capacity of 40 cubic feet per second. Despite being classified as having a low hazard potential and a moderate risk assessment, the dam is currently rated as "Not Rated" in terms of its condition assessment. The spillway of this uncontrolled dam is 20 feet wide, and it serves as a critical infrastructure for flood control in the region.
This structure, owned by the local government, plays a crucial role in managing water resources and ensuring the safety of the community against potential flooding events. With its strategic location and design features, Big Creek-Hurricane Creek R-6 stands as a testament to the collaborative efforts of various agencies in safeguarding the environment and enhancing climate resilience in Carroll County, Missouri.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
